Odd droning noise from passenger side front under braking?

Recommended Posts

I don't think this is anything major but i'd like to be sure.

 

Only seems to happen from the passenger side and is especially noticable (ie quite loud) when I have just washed the car for some reason.. this is what makes me think its just something to do with the brake disc but I dont know what.

 

But under braking I get a drone which changes dependant on speed right up until I slow down and stop. Sometimes you can hear it, sometimes you can't, and even when you can its not very loud. But as I said, you can very clearly hear it the first few times you use the brakes after washing the car.

 

Tarox discs & pagid pads, for reference.

 

Any thoughts?

 

Thanks :)

Well i'd think so - I haven't really got the facilities to get the wheel off and take a look. The pad being worn was the only think I could really think of, but it seems odd that it would only wear on one side.

 

Its due for a service in a month or so, so i'll get that checked out.

Are the discs grooved?

 

I've got grooved pagid discs and they drone a bit, especially when the grooves are full of compacted brake dust.

 

Is the noise augmented on turns or does the noise remain constant regardless of wheel direction?

It often happens that brake pads wear out faster on one side than the other. But this sounds more like a wheel bearing problem to me. If it was the brakes worn out it would be making a really bad tearing noise and you'd even see little bits of metal on the wheel instead of the normal black brake dust.

Ok - Kev - the discs are grooved and I haven't cleaned them or anything so that could possibly be the cause. The noise sounds pretty samey regardless of direction or anything.

 

And Geo - I pretty sure its not wheel bearings as I think they have been replaced already on my car in the not so distant past!

S'funny, when someone has droning disk brakes, I expected them to mention that the disks are *grooved* as one of the very first things!! :lol:
